RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 4 RHEL Program Management 2012-05-11 04:04:14 UTC 
Since RHEL 6.3 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
Comment 5 David Jaša 2012-05-11 08:57:26 UTC 
Proposing as 6.3 RC blocker.
Comment 6 John W. Linville 2012-05-14 18:05:26 UTC 
Is there an actual interruption of service?  Or just the warning output in dmesg?
Comment 7 David Jaša 2012-05-16 07:03:33 UTC 
In this case, not. But it might be the cause of bug 818672 (happened to me at the same network).
Comment 8 John W. Linville 2012-05-16 13:36:01 UTC 
If there is a cause->effect relationship with that bug, I think it probably goes the other way.

FWIW, I think that using 11n_disable=1 will prevent this from happening (albeit with the loss of 802.11n functionality).
Comment 11 Stanislaw Gruszka 2012-06-04 07:20:44 UTC 
This warning is consequence of firmware hug bug 818672, or vice versa, indicate bad condition which make firmware hung. Anyway there is no reason for having separate bug reports.

*** This bug has been marked as a duplicate of bug 818672 ***
Comment 12 Stanislaw Gruszka 2013-04-11 09:35:47 UTC 
Remove ABRT hash to avoid spurious duplicates of this bug.
